Summary
The Dental Prescale System quantifies occlusal load balance using color-changing sheets and computer analysis. This system effectively evaluates occlusal load balance in clinical settings, showing lower balance in hemimaxillectomy patients.
Area of Science:
- Dentistry
- Biomechanical Engineering
- Medical Device Technology
Background:
- Assessing occlusal load balance is crucial for dental health.
- Existing methods may lack quantitative precision.
- Hemimaxillectomy patients often present with occlusal imbalances.
Purpose of the Study:
- To evaluate the Dental Prescale System for quantitative occlusal load balance assessment.
- To compare occlusal load balance in natural dentition versus hemimaxillectomy patients.
Main Methods:
- Utilized the Dental Prescale System with color-developing test sheets.
- Employed computerized analysis to evaluate occlusal load distribution.
- Measured occlusal load balance as a percentage of the lesser occlusive load (%OLR).
Main Results:
- Natural dentate subjects showed %OLR between 39.7% and 49.4%.
- Hemimaxillectomy patients exhibited significantly lower %OLRs (0% to 31.3%) at the resection site.
- Lower %OLRs in patients were linked to structural loss and clinical adjustments.
Conclusions:
- The Dental Prescale System offers a simple, reproducible, and versatile tool for quantitative occlusal load balance evaluation.
- The system highlights significant occlusal imbalances in hemimaxillectomy patients.
- This technology is valuable for clinical assessment of occlusal load balance.
